Can LLT heartbeats communicate between NICs with different device names?
One 2-node vcs cluster, the heartbeat NICs are eth2 and eth3 on each node, IF eth2 on node1 down, and eth3 on node2 down. Does this mean the 2 heartbeat Links both down, and the Cluster is in split brain situation? Can LLT heartbeats communicate between NIC eth2 and NIC eth3? Since the 《VCSInstallation Guide》requires the 2 heartbeat Links in different networks.We should put eth2 of both nodes in the VLAN (VLAN1), and put eth3 of both nodes in another vlan (VLAN2). So in this situation heartbeats cannot communicate between eth2 and eth3. But, in a production cluster system, we found out the 4 NICs--eth2 and eth3 of both nodes are all in a same VLAN. and this lead me to post the discussion thread to ask this question: IF eth2 on node1 down, and eth3 on node2 down, What will happen to the cluster (which isin active-standby mode)?

Veritas cluster issue
Hi We have a VCS of two node. Two file systems are under VCS configured from VXVM. One file system got 100% full.Now we have rebooted the cluster node & the mount points started to show,but after some time that file system got disappear,Checked with concerned DG that also got disabed,we tried to manually import & got succeded.But after starting the volumes we tried to mount the filesystem under the specified mount point. But the below error giving--- # mount /dev/vx/dsk/bgw1dg/vol01 /var/opt/BGw/Server1 mount: /dev/vx/dsk/bgw1dg/vol01 is not this fstype # Kindly suggest what could be the cause. regards...ArupSolved2.2KViews4likes5Comments
SQL Server Service Group can't bring online on the second node
Hello everyone, Please I need a solution about my SQL cluster in test environnement. I have issues with the service group that I can"t bring it online on the second node. But in the first node its can be online without errors. For testing the intergity of the DATA on the ISCSI partition, I deleted the service group. And i mounted the partition on the second node, I recrated the service group, I can bring it online easily. When I switch it to the other node (first node on the cluster), same error, its can't be bring in online. Below some error on the event viewer about this problem : Thank you in advance for your helpSolved1.5KViews3likes5Comments

Can't locate object method "QEMU" Error During Upgrade to 6.0.x
Hi all, I have a two node VCS cluster running on two KVM Virtual Machines RHEL 5.5. VCS version is currently 5.1 SP1 RP2 and I'm trying to upgrade it to version 6.0.1.

Create service dependences for not running in the machine.
Hi to all, I like to ask about a problem for a cluster that I am creating. We do have 4 servers, running 3 services in each one of those 4 computers (one is for spare). My question is how can i make to run one service not being assigned one service to one computer, but at the same time validate that two services are not allowed to be allocated in one single computer (and be executed at the same time ) at first I think make dependences, but I can’t create circular dependences. There is any way to restrict that one service can’t be running if there is other services running in the same machine and make the same for the 3 services? Regards!!!Solved665Views3likes3CommentsShared robotic library configuration
Hi all, We need to install VCS 6.0 on RHEL 6.x. Both nodes has a robotic library attached. Backup software guide (Networker) talks about a special device file for it provided by cluster vendor, to use the robot as a HA resource. Has someone the procedure to configure that device? I cant found it yet. Regards ClaudioSolved586Views2likes1Comment
